Martian Rock Found In Morocco
daeley writes "The BBC is reporting that a rock found in 2001 in Morocco is originally from Mars, similar in composition to the 1977 Antartica find. 'The meteorite would have been blasted off the Red Planet by an impact and may hold clues to Mars' watery past... scientists say the fragments are magmatic rocks. Magmatism is the main process by which water moves from the core of planets to their surface.'"
...we find another Martian rock here on Earth. For those of you that don't think fate doesn't have a sense of irony, I think that this story proves it. ;)

Instead of us having to go to Mars, Mars is coming to us!
the Earth is littering Mars with spacecraft debris. Mars just wants a little payback.
Yeah, I saw the "magmatism is the main process by which water moves from the core of planets to their surface" thing and coughed quietly to myself *cough* *cough*.
Core differentiation generally happens REALLY early in planet's history, and it seems to me that it isn't precisely correct to say magmatism in this context, (which implies "volcanism" at least to me). Bouyancy and heat are what really moves water to the surface, since it is a) much less dense than rock (think about it) and b) not real stable at real high T.
In other words -- what moves water around is a whole mess of ugly chemistry and thermodynamics that I'll leave to my petrologist buddies to explain to me (dah? dah!) with odd pentagonal diagrams.
Uh...Nice cut and paste. Maybe you should think of something original next time.
That's odd... the piece of Mars I have on my desk is composed of entirely different substances: Milk Solids (40%), cocoa, emulsifiers, caramel, glucose etc. Scientists believe that it came from the Mare Saccharum region on Mars...
Perhaps you mean another, now defunct, Sun. Ours is still made of Hydrogen.
Almost every piece of matter on Earth came from defunct Suns (stars) what exploded at the end of their lives. The very monitor you are staring at is left-over star boom boom. It is suspected that heavy elements like gold came from supernovas or hypernovas, really big stars with really big booms, the kind that can outshine entire galaxies for a few days or weeks. So next time you see a gold ring, realize that it came from the largest kind of explosions known in the entire universe. Booms beyond human comprehension.
